make_v0() modified the apps data structure to copy an anti feature for a
specific version to all versions resulting in index-v1 and -v2 to
contain wrong anti feature annotations. This patch fixes this and adds a
test that the data structure is no longer modified.
The bug shadowed bugs in the AF implementation of -v1 and -v2 resulting
in not coping the version specific data. This is corrected as well.
This is also tested now.
For -v2 the AF dict is now sorted to make the result reproducible.
Finally The NoSourceSince AF was added as a per version and overall AF
in -v1 and is now only applied as an overall AF and the test is updated
accordingly.
